PIVOTAL SUPPORT FOR MIRRORS.

Specification of Letters Patent.

Application filed February 14, 1910. Serial No. 543,692.

To all whom it may concern:

Be it known that I, FRANK O. ANDERSON, a citizen of the United States residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Pivotal Supports for Mirrors; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the. figures and letters of reference marked thereon.

This invention relates to devices for pivotally supporting mirrors and holding the same in adjusted position at any desired angle, the objects of the invention being to provide a device which will permit the mirror to be removed from its supports when so desired and, when in place, to efl'ectually brace both the mirror frame and standards so as to prevent material independent lateral movement.

A further object of the invention is to provide a device having the desirable characteristic of separability and at the same time embody the most improved form of friction clamps for holding the mirror in its adjusted position.

The invention consists in certain novel details of construction and combination and arrangements of parts, all as will now be described and particularly pointed out in the appended claim.

Referring to the accompanying drawingsFigure 1 is a rear elevation of a mirror and supports embodying the present improvements; Fig. 2 is an enlarged detail elevation of one of the pivotal supports; Fig. 3 is an elevation of the bracket member; Fig. l is a similar elevation showing a modified construction, and Fig. 5 is a perspective view of the pintle, friction members and bearing member separated from each other.

Similar letters of reference in the several figures indicate the same parts.

Referring to Fig. 1, the letter A indicates the mirror frame and B the standards in which said frame is mounted. These parts are shown as of conventional form but it is obvious may be modified in accordance with the design and kind of furniture to which the invention is applied.

The mirror frame A is supported by the standards B through the medium of pivotal connections mounted on the frame and standards, respectively, and joined by pintles which are in frictional engagement with one of said members and detachably connected with the other whereby, when the parts are assembled, the standards and mirror frame will mutually brace and support each other, the mirror frame may be tilted at any desired angle and held by friction or. when necessary, it may be entirely removed from the standards by disengaging the pintles therefrom.

Each of the bracket members C and D is conveniently struck up from wrought metal and each is provided with right angle leaves 0, d, respectively, which when the two members are secured in position on the standards and mirror frame, as by screws F, will proj ect substantially parallel with each other in position to be connected by a transversely extending pintle. The said pintle is formed with a head G having slots or depressions g therein adapted to fit in slots cl in the leaf cl or in the slots 70 in the leaf H of the modification shown in Fig. 4. The shank of the pintle is provided with two flat faces 9 and is adapted to pass through stifi spring washers I between which the leaf 0 is clamped by upsetting the end of the shank. The washers I are provided with apertures shaped to fit the shank 9, whereby said washers will invariably turn with the pintle and in assembling the parts shown in Fig. 5 the end of the shank is upset or headed with sufficient pressure to put the spring washers under compression and thereby cause the proximate faces of the leaf 0 and washers to contact firmly and by friction resist any relative movement such as would be occasioned by turning the pintle and washers. The rounded faces of the shank of the pintle intermediate the flat faces g afford a sufiicient bearing in the aperture of the leaf 0 to support any weight which the device might be reasonably expected to bear. The flat faces of the recess 9 in the head of the pintle by engagement with the walls of the slot d effectually prevent any relative turning movement between the leaf d and pintle and the walls of said slot prevent any endwise movement of the pintle such as would tend to occur should the standards bepressed outwardly.

To enable the pintle member G to be separated from the bracket member D, the slot 03 may conveniently terminate at its upper end in an enlargement d shown in Fig. 3, or the Patented May 24., 1910. 9

said slot may extend out at the upper end of the leaf, as shown clearly in Fig. 4.

The bracket member D is preferably secured to the standard while the pintle member C is secured to the mirror frame, the parts being shown thus assembled in Fig. 1. In this position the pintles are held against rotation by the slots in the bracket members and when the mirror is swung movement takes place between the leaves 0 and the spring washers I, there being sufiicient friction between these members to require a positive pressure on the mirror frame in order to swing it in either direction. To remove the mirror frame it is only necessary to lift the same until the pintles pass out of the slots. If the form shown in Fig. 3

be employed then the standards are sprung slightly to withdraw the pintles through the enlargements 03 all as will be readily understood.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is- In a mirror support the combination with the members having base leaves for attachment to the mirror frame and standard, respectively, and outwardly projecting leaves at substantially right angles to said base leaves, one of said outwardly projecting leaves being provided with a slot and the other of said leaves being provided with an aperture therein, a pintle journaled in said aperture and having a head and a shank with flattened faces, spring washers mounted on said shank on opposite sides of the leaf and held by said flattened faces against rotation independently of the pintle, the end of said shank being upset and headed to clamp the leaf between the washers, said pintle having flat faced recesses in the projecting end for cooperation with the walls of the slot in the outwardly projecting leaf, whereby the pintle will be held against r0- tary movement.
